Abstract
A spray dispenser includes a manually actuable discharge valve at a longitudinal end thereof. The dispenser dispenses a product carried by a flexible bag. A body encompasses the bag to form a gas-containing space therebetween. The body is formed of a stiffer material than the bag. The dispenser includes a manual actuator which enables a user to collapse the body in order to compress the gas disposed within the space. The collapsed gas stores energy capable of pressurizing the bag and the product contained therein. Upon actuation of the valve, the pressurized product is expelled. When the gas energy is dissipated, the body is further collapsed to generate and store additional energy.
